What is the positive solution to the equation 0 equals negative x squared plus 2 x plus 1

The solution is x=1. This video can give you a better explanation of quadratics than I can. If you look up solving quadratics on youtube, it could probably give you a better explanation than I can. Anyways, I worked out the problem using the x method to find its factors, which turned out to be -1. In factored form, the equation is (x-1)(x-1)=0. When x=1, the equation will equal 0. 

Find 2 numbers multiply those 2 numbers the answer will be -30 but if add them together will get 7so 10 and -3 are the two numbers10(-3) = -3010+(-3) = 7(x-3)(x+10) hope this !

Ibelieve the answer is b. y=0 would make the line horizontal across the x.
